GREEN BAY - Brown County Supervisor Tom Sieber says he has filed papers to seek the Democratic nomination for the 88th District Assembly seat held by Republican John Macco.

Sieber, 41, was elected to the county board in 2012 in a district that encompasses the far northeast corner of Green Bay. He has since been re-elected three times, most recently this month.

The University of Wisconsin-Green Bay graduate is an owner of a retail business in Ashwaubenon. He and his wife, Amy, have three daughters.

He said he'll formally announce his candidacy later this week.

Macco, a 59-year-old Ledgeview resident, is a business consultant who founded a Green Bay financial-planning business and a regional retail franchise. He and his wife, Suzan, have two grown children.

Macco was elected in 2014 and re-elected in 2016.

The Assembly district includes parts of eastern Green Bay, eastern De Pere, Bellevue, Ledgeview and Glenmore.

Sieber is the second Brown County supervisor to announce he'll run for state office on the Democratic ticket. In March, Staush Gruszynski of Green Bay said he'll run for the 90th District seat being vacated by Democrat Eric Genrich. Genrich is running for Green Bay mayor.
